alt Hacker NewsTDD has always been flawed. Tests can't give you complete coverage, they are always incomplete. Though every time I say this people think I'm against tests. I'm just saying tests can't prove correctness. You'd have to be a lunatic to think they are proofs. Even crazier is having the LLMs write their own tests and think that that's proof. I'm sure it improves things, but proofs are a different beast all together.
Seems things still haven't changed in half a century

Of course tests are not proofs. For proofs I do 'make verify' :)
Tests just catch the most simple mistakes, edge cases and some regressions.
It's not meant to give you complete coverage. It's meant to guide to meeting the acceptance criteria.
